• C. It keep us warm by trapping our body heat
• D. They are made of compressed snow so it have air trapped in it which acts as an insulator

Answer 1

Answer: (C), (D)

They are made of compressed snow so it have air trapped in it which acts as an insulator

An igloo keeps you warm by trapping your body heat. Igloos are made of compressed snow. Almost 95% of this snow is trapped air, which is a good insulator. This insulation prevents the loss of body heat, and thereby keeps us warm.
